Why Get Tested?

To determine if your aldosterone and renin levels are abnormal, to help diagnose a hormonal (endocrine) disorder such as primary aldosteronism (PA, Conn syndrome).

When to Get Tested?

When you develop symptoms or signs associated with increased aldosterone production, such as elevated blood pressure, muscle weakness, and low potassium, or low aldosterone production, such as low blood pressure, high potassium, and low sodium.

Sample Required?

A blood sample drawn from a vein in your arm or a 24-hour urine sample; sometimes at specialized medical centers, blood from the kidney (renal) or adrenal veins is also collected.

Test Preparation Needed?

For a blood aldosterone and renin measurement, the healthcare practitioner may ask you to be upright or lying down (e.g., for 15-30 minutes) prior to drawing blood. You may also be instructed to avoid certain foods, beverages, or medications before the test. Follow any instructions you are given.
